From Eqs. (REF )-(REF ), using the results found in [1]} and the Limber approximation [2]}, we have
built numerically the CMB temperature power spectrum today as
\(C_{l}\,\alpha \,\frac{B_{1}}{l}cos^{2}\left(\frac{lr_{s}(z_{*})}{D_{A}}\right)+\frac{B_{2}}{l}cos\left(\frac{lr_{s}(z_{*})}{D_{A}}\right)T(l,D_{A})\nonumber \\+\frac{B_{3}}{l}T^{2}(l,D_{A})+B_{4}sin^{2}\left(\frac{lr_{s}(z_{*})}{D_{A}}\right)+...,\qquad \)
